Here is a new X_DEV play I began recently.....SBL (Symbol Technologies).
When I went to backtest this play for the bands, I chose the most recent sideways trend and then looked for at least 2 different buy and sell areas (as suggested in the User Manual). The period below fits my criteria, so I'm going with it.
I decided a 10k vest for this play is appropriate with a 50% Initial Purchase due to market conditions. If I had more confidence in an imminent reversal in the nasd, I'd have upped it to 75%. Once I had the bands positioned where I thought they should be, I started adjusting the BUY/SELL deviation multiples. It's important to note here that I didn't optimize the multiples to produce the highest return in this case. I optimized them just enough to suit my style of trade.
I can see the past buy and sell shares amounts, and am comfortable with them, so I didn't adjust the multiples higher or lower. Someone who is a bit more conservative could lower the multiples to produce smaller buys and sells shares amounts, and someone who is more aggressive could raise them to produce larger share sells or purchases. This is what I mean about using X_DEV to suit your style, risk tolerance, financial condition and comfort zone. After a while, when I have more price data and if I am sitting on a nice profit, I can always re-adjust my parameters to a full optimization mode. Until then I am happy being a bit more conservative.
